RESUMO

The results of an experimental investigation of the heat exchange in film condensation of the refrigerants R-22, R-142, and R-717 (ammonia) on horizontal knurled and smooth tubes are presented. The application of knurled tubes of this structure as a heat transfer surface made it possible to increase the coefficient of heat transfer.
